A project to create the most accurate and complete free-content encyclopedia on the Internet. Written as a collaboration of users across the Internet. Basically, the UrbanDictionary.com version of an encyclopedia, without the witless comments.

The world's largest forum for anonymous arguments. Argue with everyone in the world on any topic imaginable. You may be Stephen Hawking, so-called "expert", but you need to reconcile your views on black holes with Bob from Idaho who thinks they are portals to Narnia and find some neutral point of view that you can both agree on.

I wanted to find a place to argue about Bruce Jenner's Wheaties boxes and found Wikipedia.

Internet-based free content encyclopedia that provides entries submitted by regular Internet users, thus covering topics and issues more often ignored by the scholarly print-based encyclopedias. Not everything can be submitted, and there are policies and guidelines that must be followed. Is a distant relative to urbandictionary.com in that they are both free content Internet databases.

Wikipedia has an extensive listing of every major Harry Potter character. Even Luna gets a good-sized entry.
